Today's guidance shows good agreement for the overall forecast. 
Progression of two mid-latitude surface highs will promote brisk
to strong trades into the start of next week.  Expect the
strongest trades from Friday through the weekend as the second
high passes to the north.  Models/ensemble means anticipate some
weakening of the trades after Monday in association with a central
Pacific upper trough/surface boundary that will relax the pressure
gradient somewhat. 

Elongated shortwave energy settling over the main islands during
the next several days may close off a low for a time and
potentially enhance shower activity that will likely favor
windward/mauka areas.  Most guidance expects this feature to be
pushed eastward by next Tuesday.  The majority of rainfall should
be in the light to moderate part of the spectrum with precipitable
water values tending to be near to below climatology.  Exact
position of the potential upper low will have to be monitored as
it would not take too much of a westward adjustment from consensus
to bring additional moisture to the Big Island and vicinity.
